Calculating the Area of a Triangle

The video tutorial explains how to calculate the area of a triangle using the formula: area equals one-half times the base times the height. It provides an example calculation, clarifying that the base can be any side, as long as the height is measured at right angles to it. The tutorial also explains why the area is half of the base times height by visualizing a doubled triangle forming a rectangle. Finally, viewers are encouraged to apply their knowledge through practice questions.

What is the formula for the area of a triangle?

• Area = (base * height) / 2

• Area = base * height

• Area = base + height

• Area = (base + height) / 2

Why is the triangle area formula A = 1/2 * base * height?

• Because it is derived from the circle's area formula

• Because it represents half of the base multiplied by height

• Because it represents half of a rectangle formed by doubling the triangle

• Because it represents half of a parallelogram
